Most of the holiday skins and many legacies that would take too long to name

My account has some of the best skins in the game that you can't get anymore and even though I only have 175 skins most of them are very high quality skins and about 1/3 are legacy skins that may never come up. Grey WW and Medevil twitch cant be obtained anymore.

 

Honestly I don't think League accounts go for much. I bought an account with almost all champs for $80. The account was unranked in all seasons and had over 80 skins.

That was on a website, probably even cheaper from individual sellers.

But I'd say you could possibly sell yours for 250-300$?
